Abstract: 776,465. Expanding and stretching; rotting; drawing. ALUMINIUM LABORATORIES, Ltd. Dec. 6, 1955 [Dec. 10, 1954], No. 35829/54. Class 83 (4). A method of rectifying extruded or rolled metal sections of, for example, aluminium, comprises stretching the metal section and then subjecting the metal section to the action of a rectifying die or rollers, the die or rollers being moved lengthwise of the metal section whilst it is maintained under tension so as to impart an additional local stretch thereto. An extruded section 1 is clamped between jaws 2 on a fixed head 3 and a movable head 6 and is stretched by an hydraulic cylinder 7 moving the head 6. Rectifying rolls 8, 9, or a rectifying die, on a carriage 10 are then moved along the section from one end to the other, by a cable 12 secured to the carriage 10 and driven by an air motor, while the tension is maintained by the cylinder 7 so that the head 6 moves back a little further. The rolls are transversely adjustable on the carriage 10 and the upper roll 9 is vertically adjustable.

Abstract: 641,417. Vehicle suspensions; preventing lateral canting. KOLBE, J. Dec. 10, 1946, Nos. 36505 and 36506. Convention dates, Dec. 15, 1945 and Dec. 29, 1945. [Class 108(ii)] Relates to vehicle suspensions of the kind described in Specification 641,411 which cause the superstructure of a vehicle to bank inwardly on turns. According to the invention, each front wheel 134, Fig. 3, is suspended by upper and lower r suspension arms 114, 118 connected by universal joints 142, 150 to the chassis; the upper of these joints is displaced forwardly and inwardly relative to the lower, so that the arms 114, 118, which are connected by horizontal pivots to a wheel carrier 126, can turn effectively about an inclined axis 196 to allow the superstructure to bank, and can also move vertically during suspension movements. Both banking and suspension movements. are resisted by a spring 162 which is seated on the chassis and connected by a link 182 to an arm 172 projecting from the lever 118, the point of interconnection of the arm 172 and link 182 being offset from the axis 196 as described in Specification 641,416. In the case of the rear suspension, the upper joint 446 is displaced rearwardly and inwardly relative to the lower 448, and a carrier 454. Fig. 5, which is attached to the arms 440, 442 by horizontal pivots, is connected by a universal joint 456 and a universally-jointed link 460 to the rear axle 204; if the front wheels were carried on a rigid transverse axle, it also would be suspended in this way. The front and rear suspensions are operatively interconnected by longitudinal and transverse links 260, 188. The helical springs may be replaced by rubber torsion springs (Fig. 7, not shown), or by transverse torsion bars mounted in a housing forming part of the vehicle frame (Fig. 6, not shown); or by a transverse laminated spring, the centre of which is fixed to the frame and whose free ends are connected by links to the arms 172 (Fig. 6. not shown); the helical spring may, alternatively, be operated through bell cranks linked to the suspension arm (Fig. 10, not shown), or it may be operatively associated with the upper instead of the lower suspension arm (Fig. 11, not shown). In the embodiment shown in Fig. 8, each rear wheel 246 is independently suspended by a ring 478 carried on suspension levers 442, 464 arranged as described above; the ring allows the passage of a driving shaft and is operatively connected by a transverse link 490 to the ring of the opposite wheel; a lever 488 projecting from the ring is connected to the chassis by a link 484, which keeps the wheel parallel to the longitudinal central plane of the vehicle when banking occurs. The universal joints may each be replaced by an oblique bracket 814, Fig. 12, lying in the axis 196. and adapted to receive a pin 812 bent to form a horizontal pivot for one of the suspension arms 114.

Title: Digital impulse corrector
IPC: H04Q1/36
Filed: 1970-08-03
Abstract: 1372183 Automatic exchange systems; pulse lengthening and discriminating circuits AEI TELECOMMUNICATIONS (CANADA) Ltd 21 Oct 1971 [3 Aug 1970] 37316/70 Headings H4K and H3T  An impulse correcting circuit includes a first timer for rejecting input pulses having a duration of less than the duration TF set by the timer, a second timer of duration TV which is enabled at the conclusion of the period TF, and a logic for stretching input pulses having a duration of between TF and TV so that they each last for a period TV and for passing unchanged input pulses of longer duration than TV. The circuit is applicable to data pulse or telephone digit signalling and is useable in loop disconnect or E and M type signalling systems. The corrector shown is connected in an M lead and is effective to convert distorted incoming resistance battery pulses (see M LEAD INPUT) into corrected outgoing earth pulses (see M LEAD OUT) while maintaining the pulse rates of the two trains equal. Pulse rates of 8-12 i.p.s. are mentioned. At rest, i.e. M lead earthed, transistor T1 is conductive. Negative transients on the M lead may succeed in turning T1 off but provided they do not exceed the discharge time of capacitor C2 they are ineffective. Positive transients are of course defeated by rectifier D1. An incoming negative pulse will enable the bi-stable circuit made up of integrated NAND circuits IC4 (C, D), following the complete discharge of C2, and thereby will start monostable IC3 F. The feedback resistor R5 around the bi-stable ensures that the output pulse therefrom has a sharp waveform without any transitory oscillations. If the incoming pulse survives IC3's astable time TF, IC4 B is opened so as to turn off transistor T2. Thereafter T2 will remain off for at least a period TV set by monostable IC3 V and for the remaining lifetime of the incoming pulse if this exceeds TV. (The effects of the removal of the incoming pulse are in fact delayed by the charging time of a capacitor C1 in the input circuit of the corrector). Turn-off of T2 drops relay MO which thus connects earth to the outgoing M lead for a period at least equal to TV. The periods TF, TV are adjustable with the aid of potentiometers VR3, VR4. Power for the circuit is derived from mains battery using a Zener stabilized circuit T3, D9.
